Both the Landau Atlantis 200 2007 and the Landau Signature 2700 2013 are pontoon designs, both built in aluminium, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Landau Signature 2700 2013 measures 27,0 feet overall (2013), giving it roughly 7,0 additional feet of deck space compared to the Landau Atlantis 200 2007 at 20,0 feet (2007). Weight tells a clearer story for trailering families: the Landau Signature 2700 2013 tips the scales at 2 855 lbs - 1 430 lbs less than the Landau Atlantis 200 2007 at 1 425 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 130 hp, the Landau Signature 2700 2013 has a 40-hp advantage over the Landau Atlantis 200 2007's 90-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Landau Signature 2700 2013 is rated for 14 passengers, while the Landau Atlantis 200 2007 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Landau Signature 2700 2013 could be the deciding factor.
Both are 2-tube and 23-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity - more so than most buyers realize when comparing on paper.
Bottom line: Choose the Landau Signature 2700 2013 if your priority is putting more people on the water - it handles 14 passengers and at 27,0 ft it has the deck room to back that rating up comfortably. The Landau Atlantis 200 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
